AT5 Pulley 21-AT5 Z=16 Bore=Ø18x14mm for 10mm wide belts

Over the years we have tested many beldrive systems. For many years we have worked with XL037, because it's very common in CNC machines. The problem is that there is always a backlash between belts and pulleys. Later we started experimenting with AT5 belts and pulleys in our own products. We have seen/tested that AT5 has very low backlash and is much more suitable for the applications that we are in. What we offer here is the slimmest belt that is common, which is the 10mm wide belt version. These belts are lined with steel reinforcements, this means they are also much more stiff. For motion control this is very important. We see this belt being used with NEMA23 and NEMA24 stepper motors, and also with 100W servo systems.

This timing belt pulley is pre-machined so that the BK61 8x18mm conical clamping bushes fit perfectly. This makes it very easy to mount on a stepper motor with a 8mm diameter shaft. Or on a 40x40 Delta servo motor that also has a 8mm diameter shaft as standard.

Component features:

• Number of teeth: 16
• Designed for Belt width: 10mm
• Designed for BK61 8x18 Lt=13.4, which fits on 8mm diameter shafts
• Best low backlash belt drive system we have tested by far
• Perfect for motion control applications (Stepper and servo systems NEMA23, NEMA24,100W servo)
